I am starting to get contractors in our facility after hours that are pluggin laptops into open jacks on our shop floor in order to do xyz functions. What I would like to do (if possible) is collect all of the mac address that I know are valid and create some sort of list or table to authenticate against. That way if someone from the outside try to plug in they will get denied.

I am running a windows 2003 server. If this can be done can someone provide a step by step instruction.

If you are running a Cisco  switch, I'd advise sticky mac addresses, and shutting down the unused ports.

I can't shut down the unused ports. There are times for example one of our maintenace guys would have to plug into one to look at a machine or something (until I install wireless this is not an option).

Are you using a Cisco switch?  Another option would be a mac-address access list.  Is your network running DHCP?  If it's static, you could apply a standard ip access-list at the router allowing only the current machines, plus one more ip address for the maintenance guy(s).
